1 Cadence SPB: What s New in 16.6 Quarterly Incremental Release 003 This document describes the new features and enhancements in Cadence SPB products in 16.6 Quarterly Incremental Release (QIR) 3. The products covered are: Cadence SiP Layout and Allegro Package Designer (APD) Virtuoso SiP Architect OrCAD Capture Cadence PSpice July Product Version 16.6

2 This document describes the new features and enhancements in 16.6 Quarterly Incremental Release (QIR). Step Model Support for accurate 3D viewing Route Interconnect Optimization Productivity Enhancements Database and Miscellaneous Enhancements RF PCB Enhancements Step Model Support for accurate 3D viewing The products currently provide 3D viewing of an Allegro board drawing based on the open drawings layer visibility and object selection. The 3D viewer provides a basic rendering of board geometry, conductors, via structures and component geometry with little or no detail also referred to as block style or skyscraper viewing. The desire by users for a solution that provides more detail in component modeling to assure proper clearances and positioning that the block style viewing does not provide has been addressed thru the use of STEP models. An update to Allegro 16.6 (QIR) provides users the ability to map package and mechanical symbols to STEP models, display the STEP model in the Allegro 3D viewing tool, and to export the Allegro board drawing as a STEP model. The capability of including enclosures associated with the board is also provided for positioning and collision detection. Symbol to STEP Model Mapping STEP models are associated to Allegro package and mechanical symbol models through a mapping tool. This mapping tool sets the STEP model name to the symbol and defines offset information to correctly position the STEP model in the 3D viewer. The mapping data created is then instantiated into the Allegro symbol as a property. Step model mapping is supported in both the Symbol and PCB Editor. July Product Version 16.6

The 3D viewer relies on the currently visible layers in July Product Version 16.6

4 the Allegro PCB editor to determine what is displayed in the viewer. To view the 3D STEP models, the following CLASS/SUBCLASSES must be visible in the window: PACKAGE GEOMETRY/PLACE_BOUND_TOP PACKAGE GEOMETRY/PLACE_BOUND_BOTTOM MANUFACTURING/STEP3D_ASSEMBLY_ENCLOSURE Figure 1-2 Display of STEP models using standard 3D viewer Mechanical Step Model Support The ability to view other objects, such as shields and housings is possible if those objects are represented by STEP models. Allegro STEP model support provides the ability to map these other type objects. Once mapped to the board design, the 3D viewer will display these models where the user can then visually check for any collisions or other component placement issues. July Product Version 16.6

Mechanical STEP models must be placed within the path defined by the steppath variable. The STEP Package Mapping tool will list the mechanical STEP model as an entry in the Available STEP Models list.

5 Mechanical STEP models must be placed within the path defined by the steppath variable. The STEP Package Mapping tool will list the mechanical STEP model as an entry in the Available STEP Models list. The mapping tool contains two buttons, Add Mech and Delete Mec. The Add Mech creates a board or mechanical symbol that represents the mechanical model (enclosure) that the STEP model is mapped to. This board symbol used for mapping is placed on the board drawing origin. The offset values defined in the mapping tool position the enclosure STEP model onto the proper location and orientation in the board drawing. Figure 1-3 Import of Mechanical STEP Model Export Allegro database as Step model STEP models are used in various ways in the mechanical design environment such as checking for form and fit. Allegro STEP model support provides the ability to export an Allegro board drawing as a STEP model for use in a mechanical design environment. STEP model export supports AP203, AP204 and AP242 protocols, standard units, and various output option to minimize or maximize STEP model data. Potential for very large STEP model files exists when exporting STEP Model Parts and external copper data. July Product Version 16.6

6 Figure 1-4 STEP Export User Interface Route Interconnect Optimization A major effort targeted at improving the productivity and efficiency aspects of the interactive routing environment continues into the post 16.6 Quarterly Incremental Releases. Auto- Interactive Breakout Technology (AiBT) Split View Zoom Swap Views Auto Interactive Add Connect Detune Auto- Interactive Breakout Technology (AiBT) Auto Interactive Breakout (AiBT) technology improves user efficiency for generating breakout routing from a component, for one or both sides of a bus/interface. AiBT can be used with the new, SplitView and BundleSequence commands, to dramatically shorten the time required to develop a high-quality and properly ordered breakout solution. Menu Path for AiBT Route Unsupported Prototypes Menu Enable Auto-interactive Breakout July Product Version 16.6

7 Enabling this menu, adds new menu commands to the popup menu, that allow access to AiBT. This menu needs to be enabled for each session of. The Enable Auto-interactive Breakout menu item is currently only available when: Running Allegro with the Design Planning option, or GXL license. Running SiP or APD with the SiP license. After creating bundles within Allegro s Interconnect Flow Planning Environment, hover over a bundle then use the RMB context sensitive menu to access the relevant commands for breakout. Auto-I BreakOut Both Ends This command causes both ends of the selected Bundle/Ratsnest to automatically generate breakout routing. Auto-I BreakOut Closest End This command causes the closest end of the selected Bundle/Ratsnest to automatically generate breakout routing. The other end of the Bundle/Ratsnest remains unaffected. The closest end is determined by measuring the straight line distance from the location of the RMB menu invocation by the user, and each gather end point of the Bundle. It is recommended to use Closest End commands in the direct vicinity of one Bundle gather location so it is obvious which end is being modified. July Product Version 16.6

Auto-I. Route Trunk This command will generate the interconnect between existing breakouts. For now, the "Trunk Router" will create routing only when breakouts exist at both ends of the connection.

8 Auto-I. Route Trunk This command will generate the interconnect between existing breakouts. For now, the "Trunk Router" will create routing only when breakouts exist at both ends of the connection. In the images below, you hover over anywhere along the "Flow Trunk" and execute the command. The right image in figure below shows the results of an Auto-I. Route Trunk command. Bundle Sequences Sequences control the routing order of the rats of a bundle. The sequence is displayed visually on the canvas and the user can modify the order. The sequence order at each gather point (bundle end) is the inverse of the other end. Changes at one end of the bundle sequence also affect the other end. Bundles with multiple routing layers allowed can assign specific layers to each rat in a sequence. July Product Version 16.6

9 If a sequence does not already exist on a bundle, AiBT will generate a sequence after a breakout command completes. The sequence generated will match the breakout created on the side of the bundle where the breakout command was run. If a sequence exists, AiBT forces the breakout commands to match the routing result to the sequence. AiBT will create routing DRCs if that is the only possible way to match the existing sequence. (this behavior allows the user to see problems with the sequence and get exactly what has been specified). Split View The Split View technology is a new capability that allows the user to view another area of the design canvas, while still working with the standard main editing canvas. July Product Version 16.6

This technology is extremely effective for breakout routing solutions, where the user can now visually see both end of the bus/interface and make decisions/edits to both ends at the same time.

10 This technology is extremely effective for breakout routing solutions, where the user can now visually see both end of the bus/interface and make decisions/edits to both ends at the same time. Zoom Swap Views This command is also located on the Unsupported Prototype Menu. This command will swap what the user currently sees between the Split View canvas and Main canvas. Using this command easily allows the user to flip to the other end of the bus and perform edits/ commands in the main window. (this command improves the current use model since both canvases are not fully editable). Auto Interactive Add Connect AiAC is a new version of the existing Add Connect command. This new version provides two primary modes of operation: Manual and Auto. The Manual mode preserves the traditional functionality and behavior of Add Connect, while the Auto mode introduces a cursor based auto-routing methodology that provides cleaner route paths with fewer interactive clicks. There is also a new secondary mode of operation called Scribble. Scribble routing can be activated from within both Manual and Auto modes. July Product Version 16.6

11 Auto Mode vs. Manual Mode In open space routing, Auto and Manual mode results will be very similar. However, when routing through obstacle fields and over larger distances of the canvas, the results will diverge as Auto mode develops a unique solution using auto-routing algorithms, while Manual mode uses a direct path while bubbling around obstacles. Manual Add Connect Auto-I Add Connect Scribble mode routing Scribble is a simple routing mode that allows the user to scribble a route path onto the canvas. Once a click is made, the etch solution for the scribble path will be generated. July Product Version 16.6

Scribble provides a quick two pick methodology to generate complex route paths, along with a very controlled usage of push/shove based on the scribble path.

12 Scribble provides a quick two pick methodology to generate complex route paths, along with a very controlled usage of push/shove based on the scribble path. Scribble Path Route results Detune The Detune command automatically removes standard tuning bumps and phase bumps from cline routing. Users interactively select clines or cline segments and Detune identifies appropriate bumps and removes them from the cline, leaving the rest of the cline routing unchanged. The Detune command increases user efficiency by quickly removing timing and phase compensation, to allow easier modifications to the routing. Previously, users were forced to manually remove these bumps or delete and replace the routing. July Product Version 16.6

13 Productivity Enhancements Slide Enhancement New Variable Restores Line Width Retention to legacy behavior Allegro Drafting Prototypes Delete by Line Delete by Rectangle Offset Copy Offset Move Add Perpendicular Line Slide Enhancement The Extend Selection option in slide command now provided three choices: Segments: Extends selection to adjacent segments. By default this option is selected. Vias: Extends selection to adjacent vias. Segments and Vias: Extends selection to both segments and vias. New Variable Restores Line Width Retention to legacy behavior When the following variable is enabled, user defined line width will reset to constraint defined upon re-invoking the add connect command. This restores the behavior of the command with respect to its handling with line width overrides to pre-16.6 behavior. Variable = acon_no_width_override_retain. Allegro Drafting Prototypes Drafting command prototypes are now available for evaluation within all products via the following means. Open the User Preferences Editor from the menu by selecting Setup > User Preferences. Select the Unsupported category, check off Drafting Unsupported Prototypes, and press OK. July Product Version 16.6

Restart Allegro The unsupported drafting prototypes will now be available in the menus, either under Edit > Unsupported Prototypes or Manufacture > Drafting > Unsupported Prototypes.

14 Restart Allegro The unsupported drafting prototypes will now be available in the menus, either under Edit > Unsupported Prototypes or Manufacture > Drafting > Unsupported Prototypes. They will also be available in General Edit application mode when hovering over the applicable objects and pressing the right mouse button (RMB). Delete by Line This command allows users to remove the portion of lines, arcs, and segments lying on one side of a user-specified cut line. When invoked from the menu, the user is prompted Select object(s) to cut, after which the user is prompted Specify start point of cut line, and subsequently, after a start point is selected, Specify end point of cut line. Once the user specifies two points on the canvas, he is then prompted Select the side to remove. When the user next specifies a point on the canvas, all of the selected objects on the same side of the cut line as that point are removed. (Note that if a segment is selected, the cut extends only July Product Version 16.6

15 to the end of that segment. If a line/cline is selected, the cut extends across segments to the end of the line.) Delete by Rectangle This command allows users to remove the portion of lines, arcs, segments, and vias lying within a user-specified cut rectangle. When invoked from the menu, the user is prompted Select object(s) to cut, after which the user is prompted Specify start point of cut rectangle, and subsequently, after a start point is selected, Specify end point of cut rectangle. Once the user specifies two points on the canvas, the portions of the preselected objects lying within the cut rectangle are removed. July Product Version 16.6

16 Offset Copy This command allows users to make multiple copies of a variety of objects offset from the original(s) by a specific X and/or Y value. When invoked from the menu, the options dialog in the Allegro mini-status area is updated to provide fields for entering X and Y offset values, the number of repetitions to perform, and width/font values that can be applied to any line objects created, and the user is prompted Select the element(s) to copy. As the user selects objects, copies are created offset from the original location by the values presently specified in the options dialog. Offset Move This command allows users to move a variety of objects by a specific X and/or Y offset. When invoked from the menu, the options dialog in the Allegro mini-status area is updated to provide fields for entering X and Y offset values, and the user is prompted Select element(s) to move. As the user selects objects they are moved from their current location by the offset presently specified in the options dialog Add Perpendicular Line This command allows users to add a line perpendicular to another line already in the design. When invoked from the menu, the user is prompted Specify reference object of start point. After a pick is made, a rubber band line appears, with the reference object or start point as its July Product Version 16.6

17 first end point, and the user is prompted to specify either the end point or reference object. Once another pick is made, a line is added perpendicular to the reference object and extending from that object to the start/end point. July Product Version 16.6

To use this functionality, a new option Swap pin nets is added to the Options tab. Before pin swapping After pin swapping Note: This command is disabled if Snap and Auto Shove option is checked. July Product Version 16.6

Snap In case of multiple pins, it is now easier to pick the destination pins while snapping. The rf_snap command now displays the RF pins on the top of the drop-down list for pins.

20 Snap In case of multiple pins, it is now easier to pick the destination pins while snapping. The rf_snap command now displays the RF pins on the top of the drop-down list for pins. You can also pick the destination pin directly on the canvas to confirm the snap operation. Clearance The filter settings are now retained by the tool when initializing clearances using rf_ac_init command, even after the command is exited. Selecting User Specified Connect Pin In the SPB16.6 release, when you place, copy, edit or insert a multi-pin RF component, to choose a connect pin you need to traverse the pins sequentially. This functionality of selecting connect pin is enhanced to support the direct pick of the required connect pin on the dynamic display of the RF component outline. July Product Version 16.6

When inserting a multi-pin RF component, the new right-click menu Pick Connect Pin allows you to directly pick the desired connect pin of a multi-pin RF component as shown in the following figure.

21 When inserting a multi-pin RF component, the new right-click menu Pick Connect Pin allows you to directly pick the desired connect pin of a multi-pin RF component as shown in the following figure. Before Picking connect pin After Picking connect pin The cursor dynamics changes to reflect the selection. Choose Pick Exit Pin option to continue the routing. This enhancement is available in rf_add_component, rf_scaled_copy, and rf_add_connect commands. RF Routing Enhancements The rf_add_connect command is enhanced to provide following usability features: Line Width Retention Automatic Layer Switching Undo of Line Width Change July Product Version 16.6

22 Line Width Retention Till last release, you can override the line width values but they are not preserved. The manually set values for line-widths are now saved as a global settings and available in the drop-down list for further use. Automatic Layer Switching Starting from this release, the rf_add_connect command now supports dynamic layer inheritance. While routing with Snap to connect point, the tool now automatically selects an appropriate routing layer, based on already placed RF components. July Product Version 16.6

Undo of Line Width Change The rf_add_connect command now restores the previous line width value while routing with Variable line width and Snap to connect point.

23 Undo of Line Width Change The rf_add_connect command now restores the previous line width value while routing with Variable line width and Snap to connect point. Autoplace Enhancements In the last release, grouping functionality was introduced in the schematic for defining and managing RF groups for auto placement in the layout. To improve the autoplace performance, an enhancement has been made to support grouping functionality in the layout also. New Group menu is added for RF group creations. The details of grouping commands are as follows: Group Add: Attach a property (RFGROUP) to the selected components. Group Disband: Remove the RFGROUP property from each RF component for the specific group. July Product Version 16.6

26 Cadence SiP Layout and Allegro Package Designer (APD) Wirebond Lead Frame Bonding You can use the wirebond bond leads (Route Wire Bond Bond to Leadframe) command to automatically wire the die pads to the leads in a lead frame package. The command bonds the die pads to the leads based on net names. This command is available from the Auto Bond Lead Frame option in the Wire Bond Application mode. You can set the lead frame package type for a design using the config package type command (Route Wire Bond Set Package Type). The lead frame package type impacts which bond locations are wired on a lead. It also impacts the lead frame offset distances if the distances are defined in the wire profile set for the design. Rename Padstack The rename padstack command (Tools Padstacks Rename) allows you to change the name of existing padstacks in a design. This command changes all references for the changed padstack name such as all constraint via lists; all via, bond finger, and pin references to the padstack; and any stored name mappings. Create Fanout You can now use the Fanout commands from SiP Layout and APD to: July Product Version 16.6

27 Cadence SiP Layout and Allegro Package Designer (APD) Create clines and vias and connect them to chosen pins or symbols. Duplicate a fanout pattern from one component to all other instances of that symbol definition. Associate clines and vias with their respective component symbol instances. Disassociate clines and vias from their respective component symbol instances Package Overlay Generation for IC Designs Package overlay generation is possible in using the pkg ic overlay export command (File Export Package Overlay File for IC). This command exports an XML file describing the package geometry objects. This XML file can be opened in loaded EDI in the Floorplan view using the readpackage command to display the package overlay as a readonly overlay. Note: The feature is only available for co-design dies and is available in tools that support codesign dies. Assembly Rule Check Enhancements The minimum shape check and minimum void check Assembly Rule Checks have been greatly enhanced to eliminate a lot of DRCs because small segments were really just trying to create a smooth curve transition. On designs with many large complex shapes, the number of DRCs has been reduced significantly by eliminating these failures to make the tool much easier to use. July Product Version 16.6

28 Cadence SiP Layout and Allegro Package Designer (APD) Die Editor Enhancements You can now copy pins during co-design using the Die Editor. In addition, the Die Editor Component Editing page has been enhanced with the following options: Cursor offset in the Pins tab: In combination with the snap to functionality, allows you to add, move, or copy pins and place them at a relative offset to another object Custom in the Pins and Drivers tabs: Allows you to hide specific rats. LEF Macro in the Pins tab: When editing a distributed co-design die, allows you to pick new cell master for a pin when modifying it. The changes will be in the DIA file when it is generated from SIP to send back to the IC designer. Show Elem: Lets you display information about objects that you select on the canvas. July Product Version 16.6

29 Cadence SiP Layout and Allegro Package Designer (APD) Enhancements in Stream Import (load stream) The Stream In dialog box provides various enhancements that let you: Set the origin to use for the cursor (Cursor origin) Specify the rotation of an imported stream (Placement rotation) Select to apply a mirror geometry (Mirror around origin) Preserving Rat Bundle in Auto Assign Net Command Using the Optimize existing assignments option in the auto assign net command preserves existing rat bundles while reassigning existing assignments that had rat bundles or flow plans associated with the affected net connections. Note that bundles are preserved only for nearest match. DXF Out Default Color Mapping DXF out defaults to the color mapping which matches colors to the layers in the database (Match Database Colors), rather than defaulting to assigning a unique color index from the 256 available colors in sequential order. Unsupported Prototype Menus Starting 16.6 release, the Route Unsupported Prototype and the Tools Unsupported Prototype menus will always be visible; variable is no longer required. Do check this location periodically for prototype applications. The Tools Unsupported Prototype Layer Compare provides a set of commands, designed to be used together to analyze differences between different layers of a design or between different versions of designs. Choose the Help on Unsupported Utilities menu option for detailed help on the prototype features. July Product Version 16.6

30 Virtuoso SiP Architect Virtuoso SiP Architect Difference Viewer Enhancements In SPB 16.6 QIR 3, the difference viewer is enhanced to show the different categories of changes for bumps and drivers. Starting this release, you have the option to group the changes in different categorized based on the type of operation causing the changes. Supported categories of changes listed in difference viewer are: Move Delete Add Swap Replace Net-Assigned Net-Unassigned Place Un-place You can use the difference viewer color settings to display each group is a separate color. July Product Version 16.6

31 Virtuoso SiP Architect While updating a design, you can now either select all changes, or selectively update only a category of changes. Selective updates can be done using one of the following methods: Select all changes under a category Select individual changes While selectively updating design with all the changes in a category, it is recommended that precedence rules listed in the following table are followed. Operation ADD MOVE SWAP - REPLACE - DELETE - Operations With Higher Precedence MOVE, DELETE DELETE Changes because of operations with higher precedence are implemented first and are automatically selected. For example, changes in the MOVE and DELETE category have a higher precedence than the ADD. So if you choose to import only the changes under the ADD category, changes under MOVE and DELETE are also imported. Changes in the SWAP, REPLACE and DELETE categories can be imported independently. July Product Version 16.6
